Personally i reckon the trick with this is to make the carrier itself a trailer ie some way of lifting the tracks from the road surface my thoughts would be towards a bolt on system using the bogeys and sprockets as mounting zones so if you can imagine a gantry with two wheels on each side of the hull with flat plates on and a bar, the bar goes into the bogey jacking point the flat plates slide under the hull, you would obviously need to secure it in place, then a towing triangle on the front......... the idea being once where you needed to get to you jack up the hull and pop the sides off, second pro would be the system would take up very little space when not in use.
